a significant level of a=0.10. you obtain a sample of size n=47 in which there 366 successful observation. for this test, you should use the cumulative binomial distribution to obtain an exact p-valve.
z = ( x - np) / sqrt ( n p (1 - p) )
= ( 366- 47*0.10) / sqrt ( 47* 0.1 ( 1 - 0.1) )
= 155
p=0

You wish to test the following claim ( H a ) at a significance level of α = 0.01 . H o : p = 0.2 H a : p > 0.2 You obtain a sample of size n = 123 in which there are 35 successful observations. For this test, you should use the (cumulative) binomial distribution to obtain an exact p-value. (Do not use the normal distribution as an approximation for the binomial distribution.) The p-value for this...
You wish to test the following claim (Ha) at a significance level of α=0.005. Ho:p=0.27 Ha:p>0.27 You obtain a sample of size n=587 in which there are 168 successful observations. For this test, you should use the (cumulative) binomial distribution to obtain an exact p-value. (Do not use the normal distribution as an approximation for the binomial distribution.) The p-value for this test is (assuming Ho is true) the probability of observing... a) at most 168 successful observations b) at...
You wish to test the following claim (Ha) at a significance level of α=0.10. Ho:p1=p2 Ha:p1<p2 You obtain 13.3% successes in a sample of size n1=226 from the first population. You obtain 21.4% successes in a sample of size n2=541 from the second population. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial distribution. What is the test statistic for this sample? (Report answer...
You wish to test H:n = 70.5 versus Hau < 70.5 at a significance level of 0.10. You obtain a sample of size 27 with a mean of 61.1 and a standard deviation of 15.7. You believe that the population is normally distributed. ROUND YOUR ANSWERS TO THREE DECIMAL PLACES. (a). What is the test statistic? Do not round your interim calculations. (b). Using your answer from part (a), find the p-value. (c). What is the critical value for this...
